    Leg or foot amputation

    Amputation - foot; Amputation - leg; Trans-metatarsal amputation; Below knee amputation; BK amputation; Above knee amputation; AK amputation; Trans-femoral amputation; Trans-tibial amputation

    Leg or foot amputation is the removal of a leg, foot or toes from the body. These body parts are called extremities. Amputations are done either by surgery or they occur by accident or trauma to the body.

    Why the Procedure Is Performed

    Reasons for having an amputation of a lower limb are:

    • Severe trauma to the limb caused by an accident
    • Poor blood flow to the limb
    • Infections that do not go away or become worse and cannot be controlled or healed
    • Tumors of the lower limb
    • Severe burns or severe frostbite
    • Wounds that do not heal

    Risks

    Risksof any surgery are:

    • Blood clots in the legs that may travel to the lungs
    • Breathing problems
    • Bleeding

    Risksof this surgery are:

    • A feeling that the limb is still there. This is called phantom sensation. Sometimes this feeling can be painful. This is called phantom pain.
    • The joint closest to the part that is amputated loses its range of motion, making it hard to move. This is called joint contracture.
    • Infection of the skin or bone.
    • The amputation wound does not heal properly.

    Before the Procedure

    When your amputation is planned, you will be asked to do certain things to prepare for it. Tell your doctor or nurse:

    • What medicines you are taking, evenmedicines, supplements,or herbs you bought without a prescription
    • If you have been drinking a lot of alcohol

    During the days before your surgery, you may be asked to stop taking aspirin, ibuprofen (such as Advil or Motrin), warfarin (Coumadin), and any other medicines that make it hard for your blood to clot.

    Ask your doctor which medicines you should still take on the day of your surgery. If you smoke, stop.

    If you have diabetes, follow your diet and take your medicines as usual until the day of surgery.

    On the day of the surgery, you will likelybe asked not to drink or eat anything for 8- 12 hours before your surgery.

    Takeany medicinesyour doctor told you to take with a small sip of water. If you have diabetes, follow the directions your doctor gave you.

    Prepare your home before surgery:

    • Plan for what help you willneed when you come home from the hospital.
    • Arrange fora family member, friend, or neighborto help you. Or ask your doctor or nurse for help planning fora home health aidto come into your home.
    • Ensure thatyour bathroom and the rest of your house are safe for you to move around in. For example, remove tripping hazards such as throw rugs.
    • Ensure that you will be able to get in and out of your home safely.

    After the Procedure

    The end of your leg (residual limb) will have a dressing and bandage that will remain on for 3 or more days. You may have pain for the first few days. You will be able to take pain medicine as you need them.

    You may have a tube that drains fluid from the wound. This will be taken out after a few days.

    Before leaving the hospital, you will begin learning how to:

    • Use a wheelchair or a walker
    • Stretch your muscles to make them stronger
    • Strengthen your arms and legs
    • Begin walking with a walking aid and parallel bars
    • Start moving around the bed and into the chair in your hospital room
    • Keep your joints mobile
    • Sit or lay in different positions to keep your joints from becoming stiff
    • Control swelling in the area around your amputation
    • Properly put weight on your residual limb. You will be told how much weight to put on your residual limb. You may not be allowed to put weight on yourresidual limbuntilit is fully healed.

    Fitting for prosthesis, a manmade part to replace your limb, may occur when your wound is mostly healed and the surrounding area is no longer tender to the touch.

    Outlook (Prognosis)

    Your recovery and ability to function afterthe amputation depend on many things. Some of these are the reason for the amputation, whether you have diabetes or poor blood flow, and your age. Most persons can still be active following amputation.
